- It is also present in the gallbladder.
- It is present in the intestines.
- Smooth muscle is present in the walls of the stomach.
- It is present in the urinary system.
- It is present in the iris of the eye.

Where is smooth muscle found in the body?
Smooth muscle fibers are located
in walls of hollow visceral organs
, except the heart, appear spindle-shaped, and are also under involuntary control. Skeletal muscle fibers occur in muscles which are attached to the skeleton.
What are two examples of smooth involuntary muscles?
Smooth muscles are the nonstriated involuntary muscles that line the viscera or the internal hollow organs like, urinary tract, blood vessels, and intestinal tract.
The ciliary muscle present in the eye
is an example of smooth muscle.
What are examples of cardiac muscles?
Cardiac muscle tissue is one of the three types of muscle tissue in your body. The other two types are skeletal muscle tissue and smooth muscle tissue. Cardiac muscle tissue is only found in your
heart
, where it performs coordinated contractions that allow your heart to pump blood through your circulatory system.
What are 3 examples of smooth muscles?
Smooth muscle is found in the walls of hollow organs, including the
stomach, intestines, bladder and uterus
; in the walls of passageways, such as blood, and lymph vessels, and in the tracts of the respiratory, urinary, and reproductive systems.
What are 2 different places in the body where you can find smooth muscles?
Smooth Muscle Examples
They are found in the body’s hollow organs like
the intestines, digestive tracts, urinary bladder, ureters, and the blood vessels of the circulating blood system
. They are also found in the wall of the lungs and the reproductive system of both genders.
What is the purpose of smooth muscle?
The primary function of smooth muscle is
contraction
. Smooth muscle consists of two types: single-unit and multi-unit. Single-unit smooth muscle consists of multiple cells connected through connexins that can become stimulated in a synchronous pattern from only one synaptic input.
How do you identify smooth muscle tissue?
Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles. Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control.
What is another name for smooth muscle?
Smooth muscle, also called
involuntary muscle
, muscle that shows no cross stripes under microscopic magnification. It consists of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike striated muscle, contracts slowly and automatically.
What are the 4 types of muscles?
- Skeletal muscle – the specialised tissue that is attached to bones and allows movement. …
- Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. …
- Cardiac muscle – the muscle specific to the heart.
What are the 6 major types of muscles?
- Comparison of types.
- Skeletal muscle.
- Smooth muscle.
- Cardiac muscle.
- Skeletal muscle.
- Smooth muscle.
- Cardiac muscle.
Which of the following is an involuntary smooth muscles?
Both smooth and
cardiac muscles
are involuntary in nature. Only Striated ones we can control on our own. Striated muscles are present in the area of the body which we use for locomotion and movement.
Which muscles can be controlled involuntarily?
Skeletal muscle is voluntary and striated,
cardiac muscle
is involuntary and straited and smooth muscle is involuntary and non-striated.
Is cardiac muscle smooth?
The cardiac muscle cell has one central nucleus,
like smooth muscle
, but it also is striated, like skeletal muscle. The cardiac muscle cell is rectangular in shape. The contraction of cardiac muscle is involuntary, strong, and rhythmical.
What are the three functions of cardiac muscles?
- Heart, which pumps blood throughout the body, is made up of cardiac muscles. Three features of cardiac muscle are:
- (i) Cardiac muscles are involuntary. …
- (ii) Cardiac muscle cells are cylindrical, branched and uninucleate.
- (iii) Cardiac muscles show rhythmic contraction and relaxation throughout the life.
What organ is made of cardiac muscle?
Your heart
is actually a muscular organ. An organ is a group of tissues that work together to perform a specific function. In the case of your heart, this function is pumping blood throughout your body. Additionally, the heart is largely made up of a type of muscle tissue called cardiac muscle.
